ish-olivaceous, below white. Pupil black, iris yellow. Length 

 1 6 inches, without tail, and width 2 feet. Egg Harbor. 



(Le Sueur.) 



I have no records, except an uncertain one for Stone Harbor, 

 during October of 1897, since the one taken by Le Sueur for 

 Egg Harbor. The Stone Harbor example was called ''cow 

 fish" by the fishermen, though it may not have been this species 

 at all.
